Scans the specified attributes of FlowFiles, checking to see if any of their values are present within the specified dictionary of terms
scan, attributes, search, lookup
In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the NiFi Expression Language, and whether a property is considered "sensitive", meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the nifi.properties file has an entry for the property nifi.sensitive.props.key.
| Name | Default Value | Valid Values | Description |
|---|---|---|---|
| Dictionary File | A new-line-delimited text file that includes the terms that should trigger a match. Empty lines are ignored. | ||
| Attribute Pattern | .* | Regular Expression that specifies the names of attributes whose values will be matched against the terms in the dictionary | |
| Match Criteria | At Least 1 Must Match |
| If set to All Must Match, then FlowFiles will be routed to 'matched' only if all specified attributes' values are found in the dictionary. If set to At Least 1 Must Match, FlowFiles will be routed to 'matched' if any attribute specified is found in the dictionary |
| Dictionary Filter Pattern | A Regular Expression that will be applied to each line in the dictionary file. If the regular expression does not match the line, the line will not be included in the list of terms to search for. If a Matching Group is specified, only the portion of the term that matches that Matching Group will be used instead of the entire term. If not specified, all terms in the dictionary will be used and each term will consist of the text of the entire line in the file |
| Name | Description |

| matched | FlowFiles whose attributes are found in the dictionary will be routed to this relationship |
| unmatched | FlowFiles whose attributes are not found in the dictionary will be routed to this relationship |
